Ok, I'm really curious because this happened to me today. Today was the last day of this program I'm in, so each class had a final project. My cousin and his class made this putty stuff for people and when I got mine he was helping me stir it. He was holding my hand and helping me stir and we were talking. Then my guy friend comes up and suddenly asks, "Who's he?" I say, "My cousin. Why?" and my guy friend says, "Nothing." What's getting me worked up is the way he said it. He said it in a cold way. Any advices???

looks like ur guy friend is very jealous. i personally, would have fun with his jealousy and never explain anything. but u look innocent so explain to him that he's ur cousin and he's like a brother to u.
